When marking a transaction as a web transaction using Transaction.SetWebRequest, it is now possible to include a Host field in the WebRequest struct, which defaults to the empty string.
Bug Fixes
The Host header is now being correctly captured and recorded in the request.headers.host attribute, as described here.
Previously, the timestamps on Spans and Transactions were being written using different data types, which sometimes caused rounding errors that could cause spans to be offset incorrectly in the UI. This has been fixed.
